media-fonts/terminus-font: use fontforge for rescaling

We tackle a few issues at once here:

1. Avoid 'fonttosfnt' when converting to .otb and use fontforge instead.
2. Use one .otb file per font
3. Attempt to avoid Pango's fractioning by using 1024 em

+	# Important details (copying notes as-is):
+	#
+	# 0. Pango 1.44 now returns floating point ascent and
+	# descent, instead of integer. The functions were always returning float,
+	# all right... but so far, without a fractional part. Which makes problems
+	# too, for example in Scintilla based editors such as SciTE and Geany
+	# (there is a quick and dirty fix).
+	#
+	# 1. 'fonttosfnt' adds 0.5 to at least the logical (OpenType-scaled)
+	# character width, ascent and height. Haven't checked the physical (pixel)
+	# metrics yet. With some sizes/applications, the fonttosfnt converted
+	# fonts do indeed have extra wrong spacing, 1 pixel horizontal or
+	# vertical. It has other bugs too, but they don't seem important.
+	#
+	# 2. If you pack 2+ terminus sizes into a single .otb font file, KDE will
+	# (may? YMMV) use *only the first size*.
+	#
+	# 3. OTB has a single set of logical metrics. So, for example, the logical
+	# character width (which is relative to height) can never be correct for
+	# an .otb file including both 8x14 and 8x16.
